International Mathematics Olympiad

                                   International mathematics Olympiad:-

  • The International Mathematical Olympiad (IMO) is the World Championship Mathematics Competition for High School students and is held annually in a different country.
  • The first IMO was held in 1959 in Romania, with 7 countries participating. It has gradually expanded to over 100 countries from 5 continents.
  • The IMO Advisory Board ensures that the competition takes place each year and that each host country observes the regulations and traditions of the IMO.
  • The IMO Foundation is a charity which supports the IMO. The IMO Foundation website is the public face of the IMO.
  • This is a particularly valuable resource for people who are not necessarily mathematical specialists, but who want to understand the International Mathematical Olympiad.

Stage:-1 RMO (regional mathematical Olympiad)

  • Regional Mathematical Olympiad is held in each region normally between September and the first Sunday of December each year.
  • A regional coordinator makes sure that at least one centre is provided in every district of the region. RMO is a 3-hour written test which contains about 6 to 7 problems.
  • All high-school students up to class XII are eligible to appear for RMO. To appear for RMO, interested students should get in touch with the RMO co-ordinator of their region well in advance, for enrolment and payment of a nominal fee.
  • Each regional coordinator has the freedom to prepare his/her own question paper or to obtain the question paper from NBHM. The regions which opt for the NBHM question paper hold this contest on the 1st Sunday of December.
  • On Based on their performance in RMO, certain number of students from each region are selected to appear for the second stage. The regional coordinators charge nominal fees to meet the expenses for organizing the contests.

Stage:-2 Indian National Mathematical Olympiad (INMO).

  • Indian National Mathematical Olympiad is held on the first Sunday of February every year at different centers in different regions. Just the students who are selected on the basis of RMO from various regions are eligible to appear for the INMO.
  • It is a 4-hour written test. Its question paper is set centrally and the test is common throughout the country. Only the top 30-35 performers in INMO receive a merit certificate.

Stage:-3 International Mathematical Olympiad Training Camp (IMOTC)

  • This is a training level for the INMO certificate awardees. They are invited for a month long training camp (for junior batch) conducted in May-June, each year.
  • Also in addition, INMO awardees of the previous year who have satisfactorily completed the postal tuition throughout the year are again invited for a second round of training (called the senior batch).

Stage:-4 International Mathematical Olympiad (IMO)

  • A leader and deputy leader are chosen by the NBHM from among mathematics teachers/researchers involved in the Mathematics Olympiad activity.
  • So the team selected at the end of the camp, the leader and the deputy leader, represent India at the International Mathematical Olympiad that is normally held in July in a different member country of IMO each year.
  • The IMO consists of two written tests held on two days with a gap of at least one day. Both the tests are of four-and-a-half-hours.
  • India has 25 regions along with three independent groups that conduct Regional Math Olympiad.

Each region has its own Regional Coordinator, who is responsible for conducting RMO in his/her region & they are:-

  • Regional Coordinators have the discretion of using central RMO paper set by the HBCSE or set the examination paper themselves.
  • Regions that choose to go with the centrally prepared RMO paper have to conduct a pre-RMO to screen students for the central RMO examination.
  • The format of the pre-RMO paper and criteria for short listing student for RMO is decided solely by the Regional Coordinator.

Only students of class IX, X, XI and XII are eligible to participate in Regional Mathematical Olympiad.
However, Regional Coordinators have the discretionary power to allow any Class VIII student with exceptional mathematical talent to sit for the RMO.

Syllabus for Mathematics Olympiads-

  • Syllabus for Mathematics Olympiads (regional, national and international) is class 9thto 12thstandard mathematics.
  • The typical areas of problems are: number theory, algebra, geometry, and combinatorics.
  • The topics covered under these areas are: number systems, geometry, arithmetic of integers, quadratic equations and expressions, co-ordinate geometry, trigonometry, systems of linear equations, Factorisation of polynomials, permutations and combinations, inequalities, probability theory, elementary combinatorics,  number theory, complex numbers, elementary graph theory and , infinite series.
  • The syllabus does not include statistics and calculus.
  • Though the syllabus is roughly spread over class IX to class XII levels, still the problems under each topic are of an exceptionally high level in difficulty and sophistication as compared to the text book problems.
  • The difficulty level keeps increasing from RMO to INMO to IMO.


The International Mathematical Olympiad (IMO) is an annual six-problem mathematical olympiad for pre-college students, and is the oldest of the International Science Olympiads.[1]

The first IMO was held in Romania in 1959. It has since been held annually, except in 1980. About 100 countries send teams of up to six students,[2] plus one team leader, one deputy leader, and observers.[3]

The content ranges from extremely difficult algebra and pre-calculus problems to problems on branches of mathematics not conventionally covered at school and often not at university level either, such as projective and complex geometry, functional equations and well-grounded number theory, of which extensive knowledge of theorems is required.

Calculus, though allowed in solutions, is never required, as there is a principle that anyone with a basic understanding of mathematics should understand the problems, even if the solutions require a great deal more knowledge.

Supporters of this principle claim that this allows more universality and creates an incentive to find elegant, deceptively simple-looking problems which nevertheless require a certain level of ingenuity.

Selection procedure

  • Students who clear INMO but are not selected for International Math Olympiad (IMO) receive postal problems during the period of July to December.
  • Based on their responses, they might be invited to the pre-departure training camp for IMO directly or asked to sit for INMO again (without having to sit for the Regional Math Olympiad).

Exam Structure

  • RMO has six or seven problems that students have to solve in three hours. The syllabus for RMO basically covers pre-degree college mathematics.
  • The major areas covered in the syllabus are algebra, geometry, number theory and combinatorics.
  • Calculus and statistics are not within the scope of the exam but students are allowed to use approaches based on them to solve problems.
  • The questions generally have high difficulty level and sophistication which only increase from RMO to INMO to IMO.
  • One should go through Regional Mathematical Olympiad past year papers as well as Regional Mathematical Olympiad sample papers to fully understand what is to be expected in the exam.
